Khazar or Xazar may have come from *Qasar. The Turkic rootqaz- means "to ramble, to roam" (used in Qazaqsa or Kazakh), similar to the Common Turkickez-.
Some claimed that it came from qas- ("tyrannize, oppress, terrorize") because it is similar to the Uyghur name Qasar. Others see it as a person or tribe's name. For instance, the Chinese name Kesa for Khazars may be one of the tribal names of the Uyğur Toquz Oğuz of the Göktürks, namely the Gésà.
However, others say Kesa was not a tribal name but the name of the chief of the Sijie (思結) tribe of the Toquz Oğuz. In Middle Chinese, the name Khazars always comes before the word Tūjué (Tūjué Kěsà bù: 突厥可薩部; Tūjué Hésà: 突厥曷薩). Khazar language is extinct, while modernTurkic languages still refer to the Caspian Sea as the Khazar Sea.
No known records of the Khazar language have survived. The state was multilingual and polyethnic. The ruling elite probably spoke an eastern dialect of Shaz Turkic. The ordinary people may have spoken Lir Turkic, such as Oğuric, Bulğaric, Chuvash, and Hunnish. The Persian historian al-Iṣṭakhrī said that the Khazar language was different from any other known language. After some Khazars became Jewish, they may have written in the Hebrew alphabet, if Ibn al-Nadīm told the truth. Though they spoke a Türkic language, they might have also spoken Hebrew.
History
Origin
They appear to have come from Mongolia (蒙古) or northern China after the Xiōngnú (Huns)[dubious–discuss] were defeated by Han dynasty (漢朝) of China (Han–Xiongnu war). The tribes probably had Iranian, proto-Mongolic, Uralic and Palaeo-Siberians. The Turkic tribes might have conquered the Western Eurasian steppe as early as 463. In 552, they conquered the Rouran Khaganate (柔然汗國) and moved westwards, taking more people from Sogdia.
The ruling family might have come from the Āshǐnà (阿史那) clan of the West Türkic (西突厥) tribes. The Chinese and Arabic records are almost identical, indicating strong support for this theory. The leader might have been associated with Yǐpíshèkuì (乙毗射匱). He died around 651. Moving west, the Khazars reached Akatziroi, one of the important friends of Byzantium fightingAttila's army.
Khazaria
Khazaria is said to have emerged after 630. It is said to have come from the Göktürk Qağanate following their defeat by the Tang Dynasty (唐朝) between 630 and 650. The Göktürk armies conquered Volga by 549. The Āshǐnà clan whose tribal name was 'Türk' (the strong one) arrived in 552. They overthrew the Rourans and created the Göktürk Qağanate.
War with Tang Dynasty
The Chinese Tang Dynasty defeated the Turkic Qağanate and set up the Anxi protectorate (安西都護府) in Central Asia. The Khaganate split into several tribes. Some tribes went west to the Sea of Azov area. Ashina and the Khazars went further west. In 657, General Sū Dìngfāng (蘇定方) dominated the Turks and Central Asia. They imposed Chinese overlordship to the east of those Turkic tribes. In 659 the Chinese defeated the remaining tribes. The Khazars did not dare return.
War with Bulgars
Instead, the Khazars defeated the Bulgars further west. The Khazars Khaganate was then founded from the ruins of a nomadic empire destroyed by the Tang armies to the east, becoming the westernmost successor state of the Göktürks.
Later conquests
The Khazars conquered the lower Volga region and the area between the Danube and the Dniepr. In 670, they also conquered the Onoğur-Bulğar union and made the Onogur-Bulgar language the official language of the empire.
Khazar Empire
The empire is sometimes popularly called a steppe Atlantis. Historians often refer to this period as Pax Khazarica, which means "Khazarian peace" in Latin. The state became an international center of trade.

Kěsà (可薩) would have been pronounced as something like kha'sat in both Early Middle Chinese (EMC) and Late Middle Chinese (LMC), while Hésà (曷薩) would yield γat-sat in (EMC) and xɦat sat (LMC) respectively, where final t often transcribes –r- in foreign words.
Thus, while these Chinese forms[clarification needed] could transcribe a foreign word of the type *Kasar/*Kazar, *Gatsar, *Gazr, *Gasar, there is a problem phonetically with assimilating these to the Uyğur word Qasar/ Gesa (EMC/LMC Kat-sat= Kar sar= *Kasar).

↑Golden 2006 harvnb error: no target: CITEREFGolden2006 (help).'Oğuric Turkic, spoken by many of the subject tribes, doubtless, was one of the linguae francae of the state. Alano-As was also widely spoken. Eastern Common Turkic, the language of the royal house and its core tribes, in all likelihood remained the language of the ruling elite in the same way that Mongol continued to be used by the rulers of the Golden Horde, alongside of the Qipčaq Turkic speech spoken by the bulk of the Turkic tribesmen that constituted the militaryforce of this part of the Činggisid empire. Similarity, Oğuric, like Qipčaq Turkic in the Jočid realm, functioned as one of the languages of government.'
